Intel Bartlett Lake Revealed:P-Core Only, Up to 5.9GHz

According to Wccftech, Intel is preparing to launch its next-generation processor series, codenamed Bartlett Lake, which entirely drops E-Cores (efficiency cores) in favor of P-Cores (performance cores). Targeting embedded and edge computing applications, the flagship SKU can feature up to 12 performance cores with a maximum clock speed of 5.9GHz.

The leaked product list reveals 12 Bartlett Lake SKUs across the Core i5, i7, and i9 lines. Core i5 models are clocked between 5.2GHz and 5.5GHz, Core i7 models reach up to 5.7GHz, and the Core i9 flagship 273PQE hits 5.9GHz—200MHz higher than the Raptor Lake Refresh Core i9-14900KS.

In terms of core and cache configurations, Core i7 models come with 10 performance cores, while Core i9 models pack 12 P-Cores, catering to high-performance embedded workloads. The Core i5 series is expected to feature 6 to 8 P-Cores. L3 cache sizes are 24MB for Core i5, 33MB for Core i7, and 36MB for Core i9.

Early benchmarks of the Bartlett Lake Core i7 253PE (10 P-Cores) show that even with fewer cores, its pure P-Core architecture outperforms the Core i5-14500 (6P+8E), highlighting the significant impact of core configuration on performance.

Bartlett Lake-S is not intended for mainstream PC use, though past platforms occasionally appeared in the DIY market through certain motherboard vendors or unofficial channels. Whether similar unofficial availability will occur this time remains to be seen.
